Salmon, Kippered.--Lay the fish on a board with the tail towards you, and the back to the right hand; insert the knife at the point of the nose, and split down the backbone, or as near to it as possible. Take out the inside and the roe, and scale and wipe the fish perfectly clean; remove the backbone and every particle of blood. When clean, rub in a mixture of equal parts salt, brown sugar, and ground black pepper, about 4 large spoonfuls of each ingredient to a 10 lb. fish. Let the fish remain in the pickle 2-3 days, according to size, turning it every day. Afterwards press it between 2 flat stones in a cool place for 2-3 days more, then sprinkle it with ground pepper, and hang it out in the sun against a wall until dry, with wooden skewers to keep it flat, or it may be hung above the fireplace in the kitchen when it is warm, but not hot. After that it may be smoked for 2 days and nights in the smoke of dried seaweed and oak sawdust, or painted over with pyroligneous acid, or with Smith’s Cambrian essence. Salmon, Pickled.--Take a good salmon; cut it across in 2 or 3 pieces without splitting it; wash carefully and boil in pickle made with coarse salt and spring water strong enough to float an egg. The fish must be put down in cold pickle, and allowed very slowly to boil till it begins to separate from the bone, keeping it well skimmed all the while. Put the fish on a table to drain, and when cold pack it in a crock or keg as closely as possible without breaking the pieces, sprinkling a small quantity of powdered saltpetre, a little salt, and some bay leaves on each layer. Then cover with a pickle made thus: 1 qt. vinegar, 3 pints spring water, ¼ lb. lump sugar, 16 drops oil of cloves. This pickle will preserve any kind of fish fit for pickling, and is particularly good for oysters. These should be boiled slowly before put in it. Sardines.--The beheaded and cleaned fish are spread upon sieves, and plunged for 1 or 2 minutes beneath the surface of boiling oil in coppers. After draining a little, the fish are packed closely in tin boxes, which are filled up with pure cold oil, and soldered. The quality deteriorates with every immersion, owing to the matters disengaged by the boiling oil, and the coppers need frequent replenishing with oil.
